Accounting Technician from Pernambuco Claims to Have Won Dozens of Prizes in Mega-Sena, Quina, and Lotofácil After Switching from Random Guesses to Statistics, Strategy, and Spreadsheets.
He claims to have “hit” more than 70 times in the lottery and swears it is possible to learn the ropes. Every Brazilian has thought: “What if I hit that giant prize?”. However, most play on impulse, using birthdays, car plates, “lucky” numbers and then stare at the ticket as if waiting for a miracle. Now imagine a guy who says he won more than 70 times (not the million-dollar Sena, but various smaller prizes) and still works as a lottery researcher.
Well, that’s exactly what a person from Pernambuco said, complete with a method, lists of tens, and a golden rule: never put your money at risk.
Who is the “Lottery Researcher” Brazilian and What Does He Claim
Fascinated by mathematics, 41-year-old accounting technician Guilhermino Ferreira says he played every week in at least one lottery, always in “guess” mode: birthday dates, phone numbers of acquaintances, car plates. And, according to him, the result was predictable: he won nothing.

Does compulsive lying exist? What does science know about mythomania and why does it go beyond ‘lying too much’?
The turning point came when he decided to stop “throwing money away” and started studying ways to increase his chances in the game.
From there, he claims to have won more than 70 times and totaled about R$ 150,000 in prizes, including quads and groups in Mega-Sena and hits of 14 points in Lotofácil. He says he has never hit the Sena, the highest prize.
Today, according to his account, he works as a researcher of national and international lotteries, has a published book, maintains a website on the subject, and provides consulting for gamblers in several countries (Spain, the United Kingdom, Germany, the United States, Australia, Belgium, Portugal, and Japan).
And here comes a quote from him that needs to remain exactly as published:
“Mathematics is an exact science and can indeed help the gambler. Relying on luck is not a good business. I believe luck can be ‘improved’. For me, in a lottery, 45% is investment, 45% is strategy, and 10% is luck.”
Another equally important quote from him is the warning that avoids illusion:
“I play frequently myself, but at most R$ 100 a week. The lottery should always be seen as entertainment. You shouldn’t bet high; play with little money, but use the right numbers based on statistical data.”
Where the Tips Apply and Where Nothing Can Be Promised
He states that his guidelines apply to several modalities: Mega-Sena, Quina, Lotofácil, Timemania, Lotomania, Dupla-Sena and Loteca.
But the main point remains the most grounded: there is no guarantee of winning, so the rule is to never bet money that you cannot afford to lose.
The Tips “In Practice” (The Way He Describes)
In the book The Lottery Manual, the tips are focused on Mega-Sena, but he mentions that they can be adapted for other lotteries.
1) Frequency of Numbers: the “Hottest” Ones Make It into the Game
He states that he researched numbers with high frequency (that have come out many times) and low frequency (that have come out fewer times). The “ideal game,” according to him, should have at least two or three numbers from the most frequent group. He lists these numbers:
04, 05, 07, 12, 13, 16, 17, 23, 24, 29, 30, 32, 33, 37, 38, 41, 42, 43, 47, 49, 50, 51, 53, 54, 58, and 59.
2) No Sequence and No “Vertical Column”
According to him:
- you shouldn’t play with consecutive numbers;
- nor with numbers that fall in the same column (vertical).
3) Balanced Even and Odd Numbers
He advocates betting with the same amount of even and odd numbers.
4) The Ticket “Divided into Quadrants”
He also suggests dividing the ticket into four quadrants and choosing numbers from differentiated quadrants to “spread” the bet better.
Grouping and Expansion: When the Spreadsheet Comes into Play
Now comes one of the most talked-about points in his material: grouping and expansion.
The idea, as he explains, is to use these concepts when you’re betting with more than six numbers — he advises at least ten — trying to spend the least amount while increasing your chances of winning.
He defines it as follows:
“Grouping in lotteries is an arrangement of a certain number of numbers that guarantees a minimum prize if specific conditions are met.”
And he gives a very direct example: you can play 10 numbers in Mega-Sena and “guarantee at least the quad” if you hit five of those numbers, with calculations done via spreadsheets based on probability theories. (It’s worth noting: this depends on the conditions of the grouping and how the expansion was structured.)
If you want to check official data on prices and odds by the number of numbers, CAIXA itself publishes comprehensive tables. In Mega-Sena, for example, the probability of a simple bet (6 numbers) to hit the Sena is 1 in 50,063,860.
“But Wait!” The Real Odds Are Harsh, and Official Numbers Show This
This is where many people get excited and lose track. Even with a method, mathematics does not perform miracles: it only helps you make more conscious decisions within a game that remains a gamble.
According to official data from CAIXA:
- In Mega-Sena, the chance of winning with a normal game of six numbers is 1 in 50,063,860.
- In Quina, the probability of a simple bet (5 numbers) is 1 in 24,040,016.
- In Lotofácil, the chance of the minimum bet (15 numbers) is 1 in 3,268,760.
In other words: you can study, organize, compare patterns, and develop distribution strategies, but you can’t sell certainty.
There is another important detail that few people take seriously: the deadline to claim the prize. CAIXA warns that “prizes expire 90 days after the draw date”.
A Current Tip: You Can Bet, Keep Track, and Understand Better Without Falling for Easy Promises
If you want to play more consciously, the basics today are:
- understand the rules and official tables of each modality;
- know how resources like “surpresinha,” “teimosinha,” and group bets work;
- always check the official pages of the modalities (since prices and details may change).

Wrapping It Up: Method Helps, but the Game Remains a Game
The story of the man from Pernambuco draws attention because he does not sell a “secret code” to get rich. On the contrary: he insists on study, spending limits, and realistic expectations.
In practice, what he advocates is simple to understand:
- play for entertainment;
- use statistics to choose better;
- manage your money;
- and never confuse “more organized” with “guaranteed.”

Dicas para **** dormir, se não tiver sorte, ganhar nunca, se ele é pesquisador de loteria, e o máximo que ganhou 150 mil. Brincadeira, imagino quanto já perdeu!!!
Boa tarde! Eu concordo com tudo, eu já tirei uma quadra na Mega-Sena usando a data de nascimento, mas o jogo para mim é como se fosse uma diversão, mas jamais eu vou deixar de me alimentar para jogar.
Eu nunca ganhei na mega-sena e so perdi.
